[8u] RFR 8133489: Better messaging for PKIX path validation matching

[Martin Balao]

Hi,

I'd like to request a review for the 8u backport of 8133489 [1].

Webrev.00:

 *
http://cr.openjdk.java.net/~mbalao/webrevs/8133489/8133489.8u.jdk.webrev.00/

Changes for 8u:

 * KeyUsageMatters.java
  * 1st hook does not apply cleanly because "* @modules
java.base/sun.security.util" line (from the hook context) is not present
in 8u.

Thanks,
Martin.-
